1.Outlook on genome editing application to cattle
Journal of Veterinary Science 2024;25(1):e10-
In livestock industry, there is growing interest in methods to increase the production efficiency of livestock to address food shortages, given the increasing global population.With the advancements in gene engineering technology, it is a valuable tool and has been intensively utilized in research specifically focused on human disease. In historically, this technology has been used with livestock to create human disease models or to produce recombinant proteins from their byproducts. However, in recent years, utilizing gene editing technology, cattle with identified genes related to productivity can be edited, thereby enhancing productivity in response to climate change or specific disease instead of producing recombinant proteins. Furthermore, with the advancement in the efficiency of gene editing, it has become possible to edit multiple genes simultaneously. This cattle breed improvement has been achieved by discovering the genes through the comprehensive analysis of the entire genome of cattle. The cattle industry has been able to address gene bottlenecks that were previously impossible through conventional breeding systems. This review concludes that gene editing is necessary to expand the cattle industry, improving productivity in the future. Additionally, the enhancement of cattle through gene editing is expected to contribute to addressing environmental challenges associated with the cattle industry. Further research and development in gene editing, coupled with genomic analysis technologies, will significantly contribute to solving issues that conventional breeding systems have not been able to address.

We report an autopsy case of secondary hemochromatosis associated with multiple frequent blood transfusion for the treatment of aplastic anemia. A 23-year-old man had been diagnosed as having aplastic anemia at the age of 13. He received a whole blood transfusion, about 1280 ml, every month during the past 10 years. Recently he developed diabetes mellitus and a congestive heart failure. The autopsy revealed that multiple organs were affected by secondary hemochromatosis, including the liver, heart, pancreas, spleen, bone marrow, stomach, thyroid gland, adrenal glands, and testes. The lungs and liver showed gross and microscopic findings consistent with a congestive heart failure in addition to hemochromatosis. The details are presented. This is a case of rare secondary hemochromatosis occurring in a young man and presenting the classic histopathologic changes indistinguishable from those of primary hemochromatosis.

PURPOSE: The purpose of this study was to examine the effects of workplace spirituality and organizational citizenship behavior on nurses' performance of nursing. METHODS: This study was done over a 6 month period, with 395 nurses participants from 5 different general hospitals with 400 beds in 4 regions of Korea. Data were gathered using self-reported questionnaires from July 23 to August 21, 2015. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson correlation coefficients, and multiple regression analyses with IBM SPSS 21.0 program. RESULTS: Nursing performance showed positive correlations with workplace spirituality and organizational citizenship behavior. The significant predictors of the nursing performance by nurses were a master's degree or higher (β=.26), civic virtue (β=.19), courtesy (β=.12), 40 years of age or older (β=.09), a sense of empathy (β=.07), and a bachelor's degree in nursing (β=.06). These variables explained 39.2% of the variance in nursing performance by nurses. CONCLUSION: Based on the outcomes of this study, there is a need to develop intervention programs that can inspire nurse to show spontaneous organizational citizenship behavior, and enhance their workplace spirituality. Related variables including academic credentials should also be taken into account.

It is reported that the recurrence rate in intermittent exotropia is 20-50%. In this study, we evaluated whether the recurrence is reduced with asymmetric recession of bilateral lateral recti(LROU) in intermittent exotropia.Twenty-nine patients underwent the asymmetric LROU recession for intermittent exotropia with follow-up of 6-54 months. The amount of recession of lateral rectus muscle in deviating eye was 2mm more than in the fixating eye. Immediate postoperative overcorrection, the rate of orthophotia, and the occurrence of consecutive esotropia(ET) were analysed.The mean amount of immediate postoperative esodeviation was 16.5+/-7.4PD(0-34PD); four patients showed 0-4PD, 18 patients 11-20PD, and 7 patients showed considerable amount of ET as high as 21-30PD. Consecutive EToccurred in 6.8% of patients despite large amounts of postoeprative ET. The outcome of orthophoria was favorable, in 93.1% of patients in follow up of 6 months, 85.1% in 12 months and 78.5% in 24 months.This study suggests that asymmetric LROU recession is an effective procedure for the correction of intermittent exotropia.

To analyze a wide variety of polymorphisms in patients with endometriosis is important since this disease has a strong genetic component. Until now, more than 30 Korean studies have been performed in order to elucidate the possible role of specific polymorphisms in the susceptibility to endometriosis. The most meaningful polymorphisms in Korean patients with endometriosis came from studies investigating GSTM1, AhRR, ER-alpha, VEGF, AHSG, and TNF-alpha. However, following studies should be made to confirm the consistency of the data to have some implications in the prediction of endometriosis. In this review, we also present the future direction of the association studies in complex trait disease such as endometriosis.

8.Effectiveness of a Self-management Program using Goal Setting based on a G-AP for Patients after a Stroke.
Journal of Korean Academy of Nursing 2014;44(5):581-591
PURPOSE: This study was conducted to develop a self-management program using goal setting for patients after a stroke. The program was based on a theory-based Goal setting and Action Planning framework (G-AP), and the effectiveness of the program was examined. METHODS: A non-equivalent control group pretest-posttest design was used. The experimental group (n=30) received the self-management program using goal setting based on the G-AP over 7 weeks. The education was delivered individually with a specifically designed stroke workbook. The control group (n=30) received only patient information leaflets about stroke. RESULTS: There were significant differences between the two groups. Stroke knowledge, self-efficacy, and health behavior compliance were significantly higher (all p<.001), and hospital anxiety (p<.001) and depression (p<.001) were significantly lower in the experimental group compared to the control group. CONCLUSION: This self-management program using goal setting based on a G-AP was found to be useful and beneficial for patients in stroke rehabilitation settings.

9.Development of a Demand Model for Physician Workforce Projection on Regional Inequity Problem in Korea Using System Dynamics
Health Policy and Management 2022;32(1):73-93
Background:
Appropriate physician workforce projection through reasonable discussions and decisions with a broad view on supply and demand of the workforce, thus, is very important for high-quality healthcare services. The study expects to provide preliminary research data on the workforce diagnosis standard model for Korean physician workforce policy decision through more flexible and objective physician workforce projection in reflection of diverse changes in healthcare policy and sociodemographic environments.
Methods:
A low flow rate through the causal map was developed, and an objective workforce demand projection from 2019 to 2040 was conducted. In addition, projections by scenarios under various situations were conducted with the low flow rate developed in the study. Lastly, the demand projection of the physician workforce by region of 17 cities and provinces was conducted.
Results:
First, demand of physicians in 2019 was 110,665, 113,450 in 2020, 129,496 in 2025, 146,837 in 2030, 163,719 in 2035, and 179,288 in 2040. Second, the scenario for the retirement of baby boomers led to a decrease in the growth rate due to time delay. Third, Seoul and Gyeonggi-do account for a high percentage of demand, a very high upward trend was identified in Gyeonggi-do, and as a result, the projection showed that the demand of the physician workforce in Gyeonggi-do would worsen over time.
Conclusion
This study is meaningful in that rational and collective physician workforce supply and demand and its imbalance in workforce distribution were verified through various projections by scenarios and regions of Korea with System Dynamics.
10.Artificial Cultivation Characteristics and Bioactive Effects of Novel Tropicoporus linteus (Syn. Phellinus linteus) Strains HN00K9 and HN6036in Korea
Mycobiology 2021;49(2):161-172
Phellinus strains were collected from different areas in Korea. Of them, the fast mycelial growing strains were artificially cultivated on the oak logs to produce fruiting body. The varieties, Phellinus linteus ASI26099 (Korea Sanghwang) and P. baumii PBJS (Jangsoo Sanghwang) were grown under the same conditions as controls. Their cultivating characteristics including mycelial colonization, pinhead formation, and fruiting body formation rate were investigated on the logs. Basidiocarps of Phellinus strains HN00K9, HN6036, and ASI26099 were concentrically zonate and shallowly sulcate, and dark chestnut showing typical characteristics of Tropicoporus linteus (synonyum: P. linteus, Inonotus linteus, polyporus linteus), which is distinguishably different to PBJS. HN00K9 showed the highest yield of fruiting body among the mushroom strains. The β-glucan content in fruiting bodies of HN00K9 was 20% higher than those of other strains. Bioactive effects of polysaccharide samples from fruiting bodies of Phellinus strains, HN00K9, HN6036, ASI26099, and PBJS were assessed on cell viability and cytokine (IL-6 and TNF-α) inhibition and finally on anticancer to different human cancer cells.
